Application areas of crosslinking agent in waterbased polyurethane dispersion

For Solvent-Based PU:

• To address hydrolysis in solvent-based polyurethane (PU), consider the addition of hydrolysis-resistant agents to the formulation. These agents can enhance the material’s ability to withstand water exposure, preventing the breakdown of polymer chains.
• It’s also crucial to ensure proper curing and drying of solvent-based PU, as complete curing can improve water resistance. Proper curing times and conditions should be followed according to the manufacturer’s recommendations.

For Water-Based PUD:

• In the case of water-based polyurethane dispersions (PUD), the use of crosslinking agents can significantly improve water resistance. Crosslinking agents create stronger bonds within the polymer structure, enhancing the material’s ability to withstand hydrolysis.
• Proper formulation and precise application techniques are essential to maximize the benefits of crosslinking agents in water-based PUD. Consult the manufacturer’s guidelines for specific product recommendations and usage instructions.
